| Batteries are bulky and relatively heavy; finding a place to install the [[electrical:12v:intro#storing_power|house battery bank]] may be the biggest power-related challenge facing cardwellers. |
| |
| ==== where to put a battery ==== |
| |
| From front to rear: |
| |
| * **under the hood** - it is unlikely there is enough room under the hood for an aux battery, but some older full-size vehicles may allow it. Upside: convenient for [[electrical:12v:alternator|alternator charging]]. Downside: underhood heat is inappropriate for lithium batteries. |
| * **in the passenger area** - Upside: convenience of wiring for loads. Downside: need to secure battery to protect occupants in case of accident. Takes up living space. |
| * **in the trunk** - Upside: out of the living space. May make connection to trunk- or roof-mounted solar easier. Downside: long wiring runs from alternator to battery((if desired)) mean either expensive heavy wiring or a voltage-boosting [[electrical:12v:b2b|DC-DC charger]]. |
| * **in a carrier rack** - a secure cargo box may be fitted on a reciever hitch carrier. Upside: not taking up living or trunk space. Venting batteries are usable. Downside: same wiring issues as trunk. Cargo box may block easy access to trunk, and will increase overall vehicle length. May cause "tail dragging" on very uneven offroad surfaces |

| ==== battery types ==== |
| |
| Deep cycle batteries appropriate for off-grid use are discussed in [[electrical:12v:deep_cycle_battery|this article]]. There are some differences for cardwellers: |
| |
| * flooded lead-acid (FLA) - |
| * "maintenance free" flooded lead-acid (FLA) - |
| * "marine" flooded lead-acid - |
| * **AGM lead battery** - |
| * **gel lead battery** - |
| * **LiFePO4 lithium battery** (LFP) - |
| * **non-LFP lithium battery** |
